Model-Based Development (MBD)

Welcome to Oyindamola Olajubu who has recently joined the Department of Computing and Immersive Technology, University of Northampton as a PhD researcher on a collaborative project with GE Aviation Systems on Model-Based software development. A summary of the project can be found below.

Project Description

Model-Based Development (MBD) is seeing widespread adoption in a variety of domains within industry, especially in aviation. Industries around the world are reporting significant benefits from its use. However, the extent to which MBD can be used effectively in the software development lifecycle is unclear.

GE Aviation Systems primarily uses natural language (textual ‘shall’ statements) to express software requirements. These textual statements are often ambiguous, untestable, incorrect, missing detail, etc. Finding this out late in the development lifecycle proves very expensive. To this end, GE Aviation Systems has turned to MBD. They still use textual statements to express software requirements, but they supplement the requirements writing activity with modelling and simulation so that engineers gain a better understanding of the requirements and their faults. The models can then be refined and improved and serve as the Software Design artifacts that are used to auto-generate code. Currently, this means they have to write tests manually to test the design against the requirements. The study will investigate whether they could use models to express requirements and use those models to auto-generate test cases for testing the design model. This would then increase their productivity. To summarise, the research project will study the feasibility of model based tool support to capture requirements and automate requirements based testing.SupervisorsDr Suraj AjitDr Mark JohnsonDr Scott Turner

The data was analysed using the software VOSviewer - http://www.vosviewer.com/ free software for visualising networks. Differences in colours represents, the clusters of publications with those authors picked out by the software. The relative size of the circles is the relative number of publications listed; so for the two biggest circles/hubs it relates to 55 and 34 publications in this time period. Some relatively new authors, to the University but not to research, explains some of the 'islands' and the number of publications within it - it only reflects publications whilst at the University of Northampton.

To dig a little deeper, going to look at the two biggest 'hubs' through their NECTAR records, so potentially going …

A computing lecturer at the University of Northampton, who is researching into how the efficiency of our everyday devices, such as mobile phones, can be improved, has been awarded the best paper at two recent conferences.
Dr Michael Opoku Agyeman has written several journal papers focusing on how the next generation of technology can meet the ever increasing demands from consumers. He was invited to present his work at the 19th Euromicro Conference on Digital System Design in Cyprus and the Institute of Electrical and Electronics Engineers’ 14th International Conference in Paris.
Part of his research concentrates on whether several processing elements can be incorporated on a single chip, known as System-On-Chip, to improve the efficiency and speed of the computing systems that we use every day, from mobile phones to video-game consoles and even medical equipment…
